Transient overvoltage on overhead metal return lines of ±500 kV MMC-HVDC grid

Transient overvoltage on overhead metal return lines of ±500 kV MMC-HVDC grid

The ±500 kV half-bridge modular multilevel converter-high-voltage DC (MMC-HVDC) grid project with overhead transmission line is under construction in China at present. For MMC-HVDC grid, only one electrical grounding point is allowed and thus, the metal return lines on the same towers with positive...
